T0 a/ZZ whom t may concern:

Beit known that we, WILLIAM CRAWFORD and WILLIAM WHITSON CRAWFORD, subjects of the Queen of Great Britain and Ireland, and residents in the city of Glasgow, Scotland, have invented certain Improved Apparatus for Racking Liquids or Filling Casks orVessels with Liquids, (for parts of which We have obtainedaBritish patent, No. 605, dated January l2, 1892; a French patent, No. 231,023, dated June 21, 1893, and a German patent, No. 72,918, dated June 25; 1893,) of which the following is a specification.

This invention has for its object to provide improved apparatus for racking liquids or filling @asks or vessels with liquids, the improved apparatus being convenient and economical in use and preventing waste by automatically stopping the supply on a cask or vessel becoming full. The improved apparatus is suitable for racking various kinds of liquids,such as beverages and Oils.

In carrying out the invention asupply-valve is employed, which is arranged to be closed by a spring (or it might be by a weight) when a detent or catch-lever, which holds the valve Open, is released. The detent or catch-lever is acted on by a diaphragm, which is subjected to air-pressure in a passage or tube extending down into the cask or vessel receiving the liquid, the bottom end of the passage or tube being open, so that the liquid as it increases in depth causes au increase of air-pressure, which, acting on the diaphragm, makes it release the detent Or catch-lever on the Cask or vessel becoming full, or as full as the parts are adjusted for. If the valve is closed by the air-pressure before the cask is quite full, the valve may be opened slightly to let more liquid into the cask by turning the valvespindle, which is provided with a projecting piece arranged to act on an incline in a Inanner to raise the valve sufficiently for the purose. p Figuresl and'2 of the accompanying drawings are respectively a vertical section and an elevation, as at right angles to each other, of the improved apparatus.

The valve-box A is made with a supply-inlet nozzle A', to which, when in use, aflexible supply-pipe (not shown) isattached for the purpose of delivering the liquid from a tank or otherlarge vessel. A port A2 in the valve-box A communicates with a tube' C, which, when in use, projects down into the cask or vessel D. The port A2 is closed by a disk-valve E on the bottom end of a spindle E', which extends up through a stuffing-box A3 and has a collar E2 and handle E3 xed on its upper end, and the valve is pressed downward by a helical spring F, inclosed in the upper part of the valve-box A. To the lower part of the tube C' there is fixed an Outer tube C', surrounding it and with it extending down into the cask or vessel D when in use, and the upper end of the space between the two tubes C and C communicates by a small tube C2 with a casing G, fixed on the valve-box A and having fixed in it by means of a cover G a flexible diaphragm G2. This diaphragm G2 has fixed to its center a spindle G2, the outer end of which is forked or grooved, so as to embrace and act on one end of a catch-lever or detent H, the other end of which engages under the coll-ar E2 of the valve-spindle E when the valve is raised to the openn position. The catch-lever H is acted on by an adjustable helical spring H on a stud fixed in the Valvebox A, the spring H moving the catch-lever so as to engage under the spindle-collar E2 when the spindle E is raised. The valvespindle E has also fixed to it below the collar E2 a downwardly-projecting arm E4, the bottom end of which, when the spindle is in its lowest position and is turned, bears on a projecting incline E5 on the side of the valvepiece box A in a manner to raise the valve E slightly for the purpose of, if necessary, supplementing the supply of liquid after the automatic closing of the valve. The valve-box A has jointed to it a piece A4 with pointed prongs for supporting it steadily on the cask D when used without other support, and to retain the valve-piece A in the bunghole or inlet of the cask or vessel D there is fixed to the tube C at the side opposite to that at which the piece A4 is fitted a piece C3, having inclined pointed teeth, which engage in the edge of the bunghole or inlet.

When a cask or vessel is being filled, and

admit air when the apparatus is lifted out of the casi; or vessel D, so that the liquid in the tube O may at once run out, the inner part of this air-hole beingguardedby a strip of metal.

. stautially as described.

What we claim as our invention is 1. The herein described device for racking p liquids or lilling easks or vessels with liquids,

with thediaphragm chamber, substantially as described.

2. The herein described device for racking liquids or filling casks or vessels with liquids, comprising a valve and valve box having an inlet and a discharge pipe to extend down into the casi: or vessel, means for automatically closing the valve when the cask or vessel is nearly full, an arm on the valve spindle and an incline on the valve box on which said arm can bear, when the valve is closed, whereby on turning the valve stem by hand the valve may be re-opened to a small extent to complete the filling of the cask or vessel, sub- In testimony whereof We have signed our naines to this specification in the presence of two subscribing witnesses.
